ABSTRACT:
A steerable catheter in which a guidewire can serve a dual purpose of deflecting a bendable element at a distal end of the steerable catheter and as a guidewire to facilitate the placement of a working catheter within the vascular system. The guidewire is adapted to be slidingly received within routing eyelets or the like where one of such eyelets is disposed at a distal end of the bendable element and another near the proximal end thereof. The guidewire can be readily advanced in the distal direction relative to the steerable catheter, but tensioning of the guidewire at its proximal end serves to deflect and bend the bendable element.
